A 1.3 mu m transverse magnetic (TM) mode laser diode (LD) with a spot-size converter was fabricated and its various characteristics were investigated. At 100 mA, the power ratio of 33 dB was obtained between TM and TE mode using 0.68% tensile strained quantum wells. The device shows far field angles of 10.4 degrees and 11.7 degrees in horizontal and vertical directions, respectively, resulting in 3.1 dB coupling loss with a surface-plasmon polariton (SPP) waveguide (WG). The 3 dB alignment tolerance with the SPP-WG is 7.2 mu m and 6.8 mu m, respectively. 3 dB bandwidth is 6.3 GHz and clear eye-opening is confirmed under 7 Gbps NRZ transmission.
